I have 2 vx2235wm, just over a year old. Within a month of each other I had to replace caps to get black screen to live again. Now, I have just acquired a pink vertical line on 1 monitor, top to bottom.Any ideas. Thanks!

Solid vertical line means you have bad LCD panel due to failed TFT driving circuits.
This VX series are not built as well as the old Viewsonic used to be.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Are you sure about no bad caps? The top of the caps have to be completely flat, and bad caps can also look normal but can have high ESR, you will need meter that can read ESR of the caps.

Apple ibook crashed when on MS Word. Black screen fan running???


Sounds like you have a problem with the logic board. This appears to be a common problem with iBook G4 related to the fit of the logic board (ie motherboard) within the case.If you were to take it to apple store the likely fix would be to replace the entire logic board which is very expensive and probably not fiscally sound on a 5 year old machine. Another option would be to try to fix it yourself. If you are feeling brave you can dissemble the laptop and attempt to shimmy the logic board back into position.

Here's a link that detail the approach. http://www.coreyarnold.org/ibook/. This guy had success on two ibooks that had the same problem and they have been working for 2 years since he did his repair
Also, here is a link to a forum that may offer you a few more approaches to solving your problem. iBook G4 won't boot up - fan running & black screen - AppleNova Forums

Hope this helps, good luck!

I have the same problem with a customer's monitor (LT716S); it turned out to be damaged power supply board. As I understand it, MAG has a 3 year warranty on parts, will probably charge you a flat labor fee plus shipping. If you do not have your purchase documentation for warranty, dump it and replace. If you can, then you may wish to have it repaired.

My customer replaced theirs; I am trying to purchase replacement parts to repair...good luck.

Viewsonic vx2235wm display issues


There are many areas of the LCD monitor that can cause very much the same effect that you see. Most of the time there are capacitors that go defective.

The caps can be tested with an ESR meter. This is a time consuming job. The caps are mostly surface mount types, and will require the proper tools to change them.

Normaly the service centers will change the defective boards rather than try to service them. There is no component level service support for any of these monitors.

In the end, it would be cheaper for you to replace the monitor rather than to fix it.
